Mistress Sadie is a sadistic person. She loves to put others in pain and she does not care what happens to them. She loves it when they beg her for mercy and today she did that through her smothering fetish. She sat on this guy's face, had him lick her ass and her pussy, used a chastity device on his dick and she pinched his nipples. He was in pain and he was choking but she did not care.
Mistress Sheena did not like how this guy behaved. She had to teach him proper manners and she did so using her ass. She teased him and she got him to relax and trust her. Then she turned on him and she smothered his face using her ass. She laughed at him as he begged for mercy but she took that chance to teach him some manners which he had no option but to learn.
